Chapter 22, Problem 4A

Why are materials such as wood, fur, feathers, and even snow good insulators?

To determine

To Explain: The materials like wood, fur, feathers and snow are good insulators.

Explanation of Solution

Introduction:

A wood, fur, feathers and snow are good insulators as they don’t have any free electrons.

A wood, fur, feathers and snow are considered as a good insulator as they act as a thick dielectric that traps air in the pores of the particles. Also, they don’t have any free electrons. They are unable to transfer heat energy from one region to another.

Conclusion:

Hence, wood, fur, feathers and snow are good insulators as they do not allow the transfer of heat.
